Door hinge bolts

[MechMan]

I need to source door hinge bolts for my 86 Monte. I think I found the size. It should be M6 1.00x16 if someone could double check me please. I found some online and at lows and Home Depot. Are those good or is there a particular place that is best suited to source these from?

Mike's has ones that are close to the OE style.

Don't believe their M6, M6-1.0 is the fine thread size used elsewhere on the car - such as holding shroud, and inner skirts.
Have a good supply of desert originals, but am not doing electronic payments at this time. You'd be better off, if ur in a hurry getting some Flanged head ones from O'reillys. There's three different M8 sizes, am not going to say which thread pitch it is without making sure am correct.

I wish I wasn't in the process of finishing up my shop, I have a coffee can full of these, somewhere!

Hmmm. M10x1.5 x 30mm is the size. GM p/n 20308287. Discontinued from GM.

M10 x 1.5 x 33mm Class 9.8 is the closest dog point HWH I can find. They don't HAVE to be dog points, but it helps a ton when trying to start them in the holes. It's a Ford replacement part for N605920-S2, but essentially the same as the GM bolt, just a hair longer.

A better deal than Mike's Montes can be found at clips and fasteners, pack of 25 for 16 bucks. Mike's Montes wants 10 bucks for 6. :

According to the parts book (for Cutlass), F/D HGE to Body (M10 x 1.5 x 30). Unfortunately, they don't list a spec for the hinge to door.

But the part number is 8750275, which looks like this:

8750275 is listed as an "emergency" "Screw" as well as "Bolt" in my 86 Olds parts book. Not sure what that was supposed to mean, but it's not even a metric bolt. I'm not real sure about this one.

This is from the May, 1980 Olds parts manual showing the dimension of the bolt of 5/16"x18 x 1.125". Note that it is not metric. Several sources has this bolt, but usually it's labeled for the older A-bodies. But just looking at the listings and you could get confused. The Jan 72 shows an earlier bolt p/n of 7667647.

You're probably looking at the same book I am. I can't find that screw/bolt on any of the parts diagrams. But yes, labelled as "SCREW, F&R/D EMER HGE". My first instinct was EMER is Emergency as well. But I'm not so sure about that. However I can't think of what else it could stand for

Clips and fasteners is a great resource, I've purchased all sorts of stuff from them.
